------------------------------------
Summary: TypeError in Pyspark Linear Regression docs
Key: SPARK-34642
URL: https://issues.apache.org/jira/browse/SPARK-34642
Project: Spark
Issue Type: Bug
Components: Documentation, ML, PySpark
Affects Versions: 3.1.1
Reporter: Sean R. Owen
The documentation for Linear Regression in Pyspark includes an example, which
contains a TypeError:
https://spark.apache.org/docs/latest/api/python/reference/api/pyspark.ml.regression.LinearRegression.html?highlight=linearregression#pyspark.ml.regression.LinearRegression
{code}
>>> abs(model.transform(test1).head().newPrediction - 1.0) < 0.001
True
>>> lr.setParams("vector")
Traceback (most recent call last):
...
TypeError: Method setParams forces keyword arguments.
{code}
I'm pretty sure we don't intend this, and it can be resolved by just changing
the function call to use keyword args.
(HT Brooke Wenig for flagging this)
